To determine SASL LDAP authentication protocols supported by your DC, launch an LDAP session (e.g. . Given that this information will begin to come out over time as Microsoft enhances Teams with the IT-policy controls and documentation that existed for Skype4B, I realized that some insights can be gathered by some old-fashioned manual work: thats rightsimple network traces have proven to be hugely informational and provides a peek into the inner-workings of Teams.
